Overloaded with plot and vibrating with neon colors, it has many gags that fall flat and feels and looks vastly overproduced. Still, if you’re a kid of 8 or older and you love arcade and computer games you’ll have good fun at “Wreck-It Ralph.”

It has its share of real laughs, too, and the idea of arcade game figures having lives of their own after hours inside all that circuitry is ripe for invention.

Ralph (voice of John C. Reilly) is a villain in an arcade game called “Fix-it Felix Jr.” He’s the knuckle-dragging lout who stomps on an apartment building so Felix (Jack McBrayer), the hero, can make repairs with his magic hammer.

But Ralph would rather be a good guy for a change, and he confesses to his bad-guys support group. After the arcade closes one night, he sneaks into another game, “Hero’s Duty,” scales a building, kills the swarming Cy-Bugs and wins a medal, meeting a tough drill sergeant gal named Calhoun (Jane Lynch).

He takes his medal and then lands in a candy game called “Sugar Rush,” where a smart-alecky little girl, Vanellope (Sarah Silverman), grabs his medal. Ralph is angry at first, but then he sees that she is a lonely outcast like him, a “glitch” whose pixels sometimes come apart.

He tries to help her build a go-cart so she can win a race and raise her status, but King Candy (Alan Tudyk) has other plans. Suddenly Ralph has someone to protect.

A charming animated short, “Paperman” (G), precedes “Wreck-It Ralph.” With a delicate, hand-drawn style, it’s a black-and-white romance set perhaps in the 1950s about a young man who encounters a young woman on a train platform.

THE BOTTOM LINE: There’s a lot of toilet humor in the banter between Ralph and Vanellope in “Wreck-It Ralph.” Also, the level of mayhem and violence, even though much of it takes place in a virtual game environment made of candy, gets pretty intense in the last third of the film — chases, explosions, and one seemingly benign character turns evil, morphing physically as he does so. “Flight” R — Not for under-17s, as it depicts serious drug and alcohol abuse, “Flight” walks a sometimes clumsy line between thriller and morality play.

Denzel Washington acts up a storm as brilliant commercial pilot Whip Whitaker. We meet Whip as he awakens in a hotel with his naked girlfriend, flight attendant Katerina (Nadine Velazquez). He’s still drunk from the night before, and drinking his breakfast. She’s smoking a joint. He snorts cocaine to wake up.

They have a flight soon. Whip apparently functions in spite of his habits. He guides the plane through nasty turbulence as they leave Florida and head to Atlanta. But as they start their descent, some mechanical failure sends the plane into a dire nosedive.

Through sheer skill, Whip rights the plane in time to achieve a crash landing. His co-pilot (Brian Geraghty) is badly injured. Two flight attendants and four passengers die, but 96 people survive.

Whip, everyone says, is a hero. Then he learns from his union rep (Bruce Greenwood) and lawyer (Don Cheadle) that the National Transportation Safety Board wants to make public the after-crash toxicology report noting the alcohol and cocaine levels in his blood.

Whip refuses to concede he has a problem. While he’s at the hospital for his injuries, he meets a drug addict, Nicole (Kelly Reilly). They start a romance, but Nicole wants to stay sober, and Whip isn’t ready. Ultimately, it’s Whip himself who showily faces down his troubles.

THE BOTTOM LINE: The alcoholism and drug addiction in the film are portrayed unflinchingly and unattractively and can be seen as cautionary messages. The opening scene includes frontal female nudity. There are some nonexplicit sexual situations. Characters use strong profanity. Scenes involving the plane flying through a storm, and then the catastrophic equipment malfunction, are harrowing.
